IMPROVEMENT IN SASH-LOCKS.

Specification forming part of Letters Patent .No. 204,096, dated May 21,1878 application filed April 8, 1878.

To all whom it may concern:

4 Be it known that I, GEORGE B. SARGHET, of Charleston, in the county ofOoles, and in the State of Illinois, have invented certain new anduseful Improvements in Sash-Locks;

and do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention relates to sashfasteners; and it consists inthe combination, with a case, of two bolts having curved recesses, andprovided-with stops extending in opposite directions through slots inthe case, and a double reverse-action tumbler having a slotted hub, andalso in hooks or lugs formed at the ends of the double-action tumbler,in combination with the bolts, all as hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which pFigure 1 is an end view of the sash-lock, showing the key at the sidethereof. Fig. 2 is an interior view of the lock. Fig. 3 is a detailedview of the lock-tumbler, and Fig. 4 shows the application of myinvention to a window frame and sash.

A represents the lock-case, provided at top and bottom with a perforatedlug, B, for the fastening-screws, the body of the lock-case being,mortised into the window-jamb at or near the center, at the junction ofthe two sashes. In recesses formed at the top and bottom inside of thecase are placed two sliding bolts,O and O, which are provided,respectively, with projecting stops D and D, extending in oppositedirections through slots in the case A, the upper stop, D, beingintended to work in the upper sash, and the lower stop, 1), for thelower sash.

The bolts 0 G are formed with curved recesses a a on the faces that areopposite each other--that is to say, in the'under side of the top boltand in the upper side of the bottom bolt. In these recesses work theends of a tumbler, D, which is pivoted in the center of the lock, saidtumbler being provided with a slotted hub, b, for the insertion of akey, F. This key has a flange, e, on one side to fit in the slot of thehub.

By turning the key F to the right, the up-- per end of the tumbler D,moves the upper bolt and stop back, while the lower bolt andstop remainin position. By areverse motion the lower bolt and stop are thrown back,while the upper bolt and stop are held in position.

Spiral springs d d are placed, respectively, behind the bolts O O tothrow the same outward. As either bolt and stop is thrown back thecorresponding sash can be raised or lowered.

he ends of the tumbler D are provided each with a hook or lug, i, asshown, by which, when either bolt is thrown back and the sash unlocked,the bolt is held back, thereby affording the operator a chance to useboth hands to raise and lower the sash.

The lid A of the case Ais secured by a single screw at w.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. In a sash-lock, thecombination, with the case A, of the bolts 0 0, having recesses a a, andprovided with the stops D D, extending in opposite directions throughslots in the case,-the springs d d, and the double reverseaction tumblerD having slotted hub 1), substantially as and for the purposes hereinset forth.

2. The hooks or lugs i '5, formed at the ends of the double-actiontumbler D in combination with the bolts O O,for the purposes herein setforth.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of March, 1878.

GEORGE B. SARGHET.
